Sgt. Jason Halifax says police were called Wednesday morning after a city worker found a bag near an intersection. The worker picked up the bag and drove into Union Park, then heard metal rattling inside. He stopped, looked inside the bag and found what appeared to be two pipe bombs.

The worker put the bag on the ground and called police.

The department’s bomb squad responded and put the items into a trailer designed for explosives. The items were taken to another site where they were dismantled.

Technicians say the items contained “energetic material” that could have exploded if they’d been ignited.
